An algorithm for breaking polygons into triangles and finding convex hull of a polygon that can be used for any planar polygon in space.

The PNGBitmap package reads and writes Portable Network Graphics bitmaps into the kernel of Mathematica. The images can be manipulated, written and used as textures for ...

We illustrate thevibrational modes of a drum shaped like the Koch snowflake. Vibrational modes are computed using a fairly standard finite difference technique applied to a ...

Functions f (x, y) of two variables with values in the field of complex numbers (e.g., analytic functions) are often considered abstract mathematical objects which are ...

The Johnson-Neyman ANCOVA, used when nonhomogeneity of within-group regressions is present, poses special computational and plotting problems when three covariates are used. ...

This package produces unfilled histograms, with a few options that work much like those of built in functions such as Plot. It also allows a convenient interface to the ...

Plot Julia and Mandelbrot sets and the attraction basins of roots of z^n-1 (for n arbitrary real number) equation obtained by the Newton-Raphson method.

The shape of any star is determined by the gravitational forces within its environment. A star that is unaffected by gravitational forces other than its own should be ...
